"as our principal executive officer"
The principal executive officer is the highest-ranking manager who leads a company’s overall strategy, operations and public communication—often acting like the captain of a ship who sets direction and makes final calls. Investors watch this person because their decisions, credibility and ability to deliver results shape company performance, risk and market confidence, and changes in that role can directly affect stock value and corporate accountability.
